Okay,
I got it, I am crazy.
This is the first time and probably the last time I will go to Europe. I just want to soak in as much culture as I can. I don't want to fly anywhere once I am in Europe. I want to rent a car and drive so that I can enjoy the countryside as well as the culture.
What do y'all think about using Milan as a base? It is almost in the middle between Rome and Paris. I could do day (or more) excursions in all directions from there.
I want to thank all of you for helping me not make mistakes so that I can truly enjoy this once in a lifetime trip.
